Struct SimulatedScheduler 

pub struct SimulatedScheduler { /* private fields */ }

Simulated scheduler that generates timer events deterministically.

Instead of waiting for real time to pass, advance() jumps the clock forward and collects all timer events that would have fired in that window.

Implementations

impl SimulatedScheduler

pub const fn new(start_time: DateTime<Utc>) -> Self

Create a new scheduler starting at the given time.

pub fn register_timers(&mut self, configs: Vec<(u64, Option<u64>, String)>)

Register timers from engine configuration.

Each tuple is (interval_ns, initial_delay_ns, event_type).

pub fn advance(&mut self, duration: Duration) -> Vec<Event>

Advance the clock by duration and return all timer events that fire.

Events are returned in chronological order. Multiple events from the same timer are generated if the advance spans multiple intervals.

pub const fn now(&self) -> DateTime<Utc>

Get the current simulated time.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
